Abstract (en)
[origin: WO2014090528A1] The invention relates to a longitudinal sealing device (1) for producing a sealed longitudinal seam (2) on a packaging material (3) which has a tubular portion (4) and a seam portion (5) that adjoins the tubular portion (4) and comprises the sealed longitudinal seam (2). A first layer (6) of the packaging material and a second layer (7) of the packaging material lie one above the other in the seam portion (5). The tubular portion (4) lies above a transport plane (T) of the longitudinal sealing device (1), and the seam portion (5), lying below the transport plane, is moved along a running direction (L) parallel to the transport plane (T). The longitudinal sealing device (1) comprises a positioning device (8) in order to position the two layers (6, 7) relative to each other, a heated sealing roller pair (9) in order to provide the sealed longitudinal seam (2) between the two layers (6, 7), and an unheated conveyor roller pair (10) arranged downstream of the sealing roller pair (9) when seen in the running direction (L). The sealing roller pair (9) comprises two sealing rollers (9a, 9b), a sealing lateral face (17) of which contacts the packaging material (3), and the conveyor roller pair (10) comprises two conveyor rollers (10a, 10b), a conveyor lateral face (18) of which contacts the packaging material. The sealing lateral face (17) of the sealing roller pair (9) is offset relative to the conveyor lateral face (18) in a direction (S) perpendicular to the transport plane.
